Calling Sequence

      matplot, img


      img = 8-bit image scaled for display. in

Keyword Parameters


        XAXIS=x, YAXIS=x Optional x and y axis arrays.
        VMIN=vmn, VMAX=vmx = Image min and max data values.
          These are the values that are displayed as
          0 and 255. Def: 0, 255.
        POSITION=pos Over-ride default image potision.
        TITLE=tt Image title (def=none).
        XTITLE=tx Image X axis title (def=none).
        YTITLE=ty Image Y axis title (def=none).
        BTITLE=btt Bar title (def=none).

        Some keywords known by PLOT may be given, such as
          CHARSIZE=csz, ...


Common Blocks


      Notes: Can use IDL color tables. Do first:
        device,decomp=0 & loadct,3
        Also the image x,y scaling info is embedded and may be
        at a later time such as when a saved image of the plot
        has been reloaded. After loading use xcursor to see if
        the image x,y coordinates are known. If not call
        set_scale to set them.
